Each nesting season it leaves the botanical garden and returns around late August or early September. We have never located it's nest but this is what I suspect happens with this adult Red-tailed Hawk.
Over the last few weeks it has made it's presence known around the botanical garden and the juvenile RTH I've been photographing since early March has not been seen since. My guess is this adult has driven it out of the area.
I know I've been photographing it since 2008 when I first started going to the botanical garden because of the middle talon on it's right foot and my guess is it's a female due to it's size.
It's more wary of humans but it doesn't fly away when it sees someone and it likes to perch higher in the trees unlike the juvenile hawk who preferred to perch about 8'-10' off the ground. This one is seen on the ground on occasion though.
I have yet to get a decent image of it I'm happy with but with patience my hope is I will be at the right place and right time.
